SPECIFICATION forming part Of Letters Patent No. 673,480, dated May '7', 1901.

Application filed April 3, 1897- erial No; 680,597. (No model.)

To all whmn it may concern.-

Be it known that I, LEOPOLD SELLNER, a subject of the Emperor of Austria-Hungary,

residing atVienna, in the Province of Lower Austria, in the Empire of Austria-Hungary, have invented certain new and useful Iniprovements in Apparatus for Signaling by Night; and I do hereby declare the following tobe a full, clear, and exact description of'the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had tolthe ac-1 companying drawings, and to letters and figures of reference marked thereon, which form a part of this specification.

This invention has for its object certain improvements in night signaling apparatus, suchasshown and described in my application for patent filed March 28, 1896, Serial No. 585,248. I y 1 The apparatus may consist of a single sigred'and white-and so placed as to be visible from all point-s of the compass, the lantern being of course ofcylindricalform in crosssection and having two uninterrupted lighttransmitting zones. With such a lantern five signals only can be produced or made namely,continuous white, continuous red, intermittent white, intermittent red, and alternate white and red. In order to increase the scope of the apparatus, I employ two such lanterns, whereby the number of signals can be increased to thirty, one of the lanterns being used for the five fundamental signals order that such signals may be readily distinguished from a distance, which would not b,ethe case if they wereprod ucedor made in one and the same lantern, andfor -this purpose I-locate the lanterns at a proper distance apartas,for instance, at the head of a mast and near the ground or deck of a ship.

1 Two such lanterns may, therefore, constitute a signal-station whenever it is possible to so locate the lanterns that lhesignals made can be seen from all points of the compass, which under most circumstances is desirable, if not absolutely necessary, bothat sea and on land. Such an arrangement of two signal-lanterns on board ship is usuallyimpossible, owing to upper-deck structures, 850., and in order that the signals may be seen from all points of the compass I employ three lanterns, one at a masthead and the other two fore and aft, as

near the main or upper'deck as possible, as

shown in Figures 2, 2, 3, and 3 so that the signals made with the upper lantern I can be seen from all points of the compass and those made with each lower lantern II and II over an arc of about two hundred and seventy degrees. In this case, therefore, three lanterns constitute a signal-station, each signal-symbol made in one of the lower lanterns, as 11, being simultaneously made in the other lantern II to render the signal made by the three lanterns visible from all points of the cover of the transmitter-casing, means controlled by said lever being likewise provided for producing a permanent record of each signal made and exposing such record to view as the signals are made, so that they can be read by the operator and their accuracy ascertai ned at once. The intermittent and alternate color signals or signal-symbols are produced by means of an automatically-operated switch combined with means for determining the period of exposure and whereby such period of exposure is rendered uniform for all intermittent or alternate color signals or symbols, substantially as described in my application for patent above referred to. \g

The present invention has for its object certain improvements in the construction of the signaling-lanterns witha view to afiord mitter contactcylinder or block to facilitate and simplify its connection with the automaticaIly-oper'atedswitch for the production; of intermittent or alternating color signals or; signal-symbols and an improvement infthe:

ready access to their interior parts and to readily fix them in their several positions and in the provision of meansswhereby a constant source of electric. light is dispensed with by diverting the light-current-from the incandescent. lamps during the time intervening between the signals'or signal-symbols or the time intervening between thesending of messages and while the light-circuit remains closed for the purpose ofprolonging the usefulness of the incandescentlamp filaments.

The invention-has for'its further object an improvement in the COllSlZIllClrlOHiOf the transcons'truc'tion of the switch by means of which .these sign als are produced, so that itwill perform the same function as the ,two switches described in myapplication above referred to. The invention has for, its 'further object certain improvements in the signal-recording which- Figst l an r Show togetherin elevation a night-signal station comprising three sig-- nal lanterus I, II, and II, together with the tern-magnets.
